Speaking on Adelaide’s 5AA radio program this morning Turnbull shared his thoughts about Walkers’s actions in a way we can only liken to a scolding from dad, which usually runs something along the lines of: “I’m not angry, I’m just disappointed”.

Turnbull said: “Certainly the young man involved needs to have a very hard look at himself and I am sure will be considering his future carefully.

“They apologised to the court and that was appropriate and they’re home, or on their way home, and that’s good.”

In July Walker was appointed innovation policy adviser to Defence Industry Minister Christopher Pyne.

In Sepang magistrate’s court, the men read out an apology and expressed remorse for their actions, saying it was “purely an error of judgment” and “moment of folly”.

“We are truly sorry for disrespecting the Malaysian flag and people,” they said.

A spokeswoman for Pyne told news.com.au the matter was being “handled appropriately by the Australian High Commissioner”.
